SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 748,921, dated January 5, 1904.

Application filed May 11, 1903.

To all whom it may concern:

Be it known that we, CAMILLE BRUN and GUSTAVE BRUN, citizens of the French Republic, residing at Lyons, Rhone, France,

have jointly invented certain new and useful embodiment of the invention.

, Figure 1 is a plan view of a shuttle with the spindle down and the quill thereon, but the Improvements in Shuttles, of which the following is a specification.

This invention aims to provide an improved loom-shuttle of the same general character as that described in the application for patent of Brun and Brun, Serial No. 153,435, filed April 20, 1903. It is specially designed for operating or controlling mechanism for stopping the loom or for supplying new weft or for similar purposes. Looms having mechanism of this kind are well'known. An example of such a loom is shown in the patent of' Brun, Brun,

. and Bicking, No. 714,655, granted December 2,1902. this application are specially designed for operation with the loom mechanism of said patent, though the invention contemplates, broadly, a shuttle adapted for use with various other loom mechanisms. For this purpose the invention provides a memberadapted to control said loom mechanism, which member is held in, inoperative position by the thread in the shuttle until the latter is nearly exhausted, when the mechanism-controlling member is released and moved to its operative position to substitute a new weft-supply or to stop the loom. In order to facilitate the application of the thread onto the spindle of the shuttle, a device is provided which is connected at one end to the mechanismcontrolling memberand which at its other end is held inward against the spindle, so that the thread may be quickly and easily introduced without catching under the end ofv such device. The invention provides also means for moving the said member to its inoperative position and moving the said device inward as the spindle is turned up, thus facilitating the application of the thread around such device.

The shuttle mechanism described is specially adapted for use with thin walled quills or cop-tubes, of paper or the like, which carry the shuttle-thread, and it is preferred to use The specific improvements shown in Serial No. 156,569. (No model.)

such a quill, which has certain advantages hereinafter pointed out.

Various other points of improvement are specified in detail hereinafter.

The accompanying drawings illustrate an thread exhausted from the quill. Fig. 2 is a horizontal section of the same, taken on a plane just above the top of the spindle.

Fig. '3 is a horizontal section of the same through the center of the spindle, but showing a load of thread on the spindle, as it will be in the running of the shuttle. Figs. 4 and 5 are horizontal sections with the shuttle-spindle turned up, the spindle being cut on the lines 4 4 and 5 5, respectively, of Fig. 3.

Referring to the embodiment of the invention illustrated, the member for controlling the loom mechanism is shown as a transversely-movable pin A. A link B is connected at its forward end to the pin A either directly or through intermediate mechanismsuch, for example, as the arm G shown. The link B at its rear end is held inward against the spindle, as by having such end enter a slot D in the spindle.

The pin A reciprocates transversely in a tube E, which forms a hollow shaft about which pivots the spindle F. A spiral spring G abutting against a pin H at one end bears at its other end against the pin A to force the latter into its outer operative position. During normal running the link B, or at least a considerable portion thereof, is surrounded by the thread J and is thus held close up against the spindle, and thus in turn holds the pin A in its innermostinoperative position against the pressure of the spiral spring G.

The quill or cop-tube K is of paper or the like. Such a quill permits of carrying a much larger load of thread in the shuttle than the ordinary wooden or other thick quills, is cheap, and effects a considerable saving in cost of transportation, duties, &c., on v the filled cops. A longitudinal opening L, preferablya mere slit, in the base portion of the quill registers with the link B and permits the latter to be moved outward under the pressure of the spring G when the thread surrounding the base of the quill is nearly ex hausted.

A wire cam M serves to automatically forcethe pin A inward as the spindle is turned up, the arm 0 of the pin bearing against the cam M and being turned upward or downward with the spindle by means of pins N, projecting from the heel of the spindle and engaging the arm 0 above and below. This cam is claimed, broadly, in the application of Brun and Brun above referred to.

The operation of the several parts of the improvement being clear, the operation of the whole may be briefly stated as follows: To prepare the shuttle for use, the spindle F is turned upward to the position of Figs. 4 and 5, drawing inward the pin A and the link B. A groove 0 is provided in the spindle, in which lies the intermediate portion of the link B, so that there is no obstacle to the application of the thread on the spindle. The quill carrying the load of thread is slipped over the spindle, the position of the end of the link 13 within the surface of the spindle permitting this to be done without danger of injury to the paper quill or the threads, the quill being arranged with its slit L coinciding with the link B. The spindle is then turned down to the running position, Fig. 3, and the thread J holds the link B in and the pin A in its inoperative position. The shuttle is then placed in the loom and operates in this position until only a few turns of the thread are left, when the pressure of the spring Gr overcomes the resistance of the threads about the link B and forces out the pin A, which operates the weft replenishing or stopping mechanism.

The link B might be of course attached to the spindle at its outer end and freely engage the pin A at its inner end.

The broad features ofinvention not claimed herein are covered by our application,No. 156,570, filed concurrently herewith. The present shuttle is primarily distinguished from the, shuttle shown in said application in the permanent holding of the end of the link B inward against the spindle, and there are other diiferences in detail which will be obvious.

Though an embodiment of the invention has been described herein with great particularity of detail, yet it is to be understood that the invention is not limited to the particular embodiment disclosed. Various modifications thereof in detail and in the arrangement and combination of the parts may be made by those skilled in the art without departure from the invention.
